So, I started going through different themes hoping one would work, and I came across one called X2 that actually showed comments, but I don’t care for the look of the theme. But, I figured if I came across one, then there has to be more, right?

BuddyPress plugin supplies the template files UNLESS the theme has included them. Only BuddyPress specific themes would include the files. That’s why I asked you to switch to Twenty Twelve so it would use the files from the BP plug folder.

It may be a plugin causing issue. You can deactivate plugins one by one and test each.

I have searched through at least 100 themes, and I’ve found two that show comments to people who aren’t logged in: x2 and Custom Community. Both of these themes appear to be made by the same person, and I really don’t care for either of these themes.

I would like to use Twenty Fourteen, and I have not been able to find anyone using this theme, who is also having this problem.

Also, the plugin BuddyPress Sitewide Activity shows all comments to people who are not logged in, but I don’t want that in my sidebar, and it doesn’t solve the groups problem.

If it is a problem with WordPress being in a subfolder, what would allow these two themes and the plugin to still work?
